In Animal Crossing New Horizons, it seems that any interior design can be perfectly restored with be the varirety of ACNH funiture sets, such as Science Lab and library. In this design, the creator only used Lab-Experiments Set, Chalkboard, Den Desk, Wooden Bookshelf, Skeleton and other furniture to establish a perfect laboratory research room. You can either conduct scientific experiments here or sit down and read and learn. And cleverly added some bathroom supplies to make the room more practical and functional.
